Detailed Description

\inmodule QtGui

Since: 5.0

The QWindow class represents a window in the underlying windowing system.

A window that is supplied a parent becomes a native child window of their parent window.

An application will typically use QWidget or QQuickView for its UI, and not QWindow directly. Still, it is possible to render directly to a QWindow with QBackingStore or QOpenGLContext, when wanting to keep dependencies to a minimum or when wanting to use OpenGL directly. The \l{Raster Window Example} and \l{OpenGL Window Example} are useful reference examples for how to render to a QWindow using either approach.

Constructor & Destructor Documentation

◆ QWindow()

QWindow::QWindow	(	QWindowPrivate &	dd,
		QWindow *	parent )

protected

Creates a window as a child of the given parent window with the dd private implementation.

The window will be embedded inside the parent window, its coordinates relative to the parent.

The screen is inherited from the parent.

Member Function Documentation

◆ accessibleRoot()

QAccessibleInterface * QWindow::accessibleRoot ( ) const

privatevirtual

Returns the accessibility interface for the object that the window represents.

See also: QAccessible

Definition at line 2222 of file qwindow.cpp.

◆ close

bool QWindow::close ( )

slot

Close the window.

This closes the window, effectively calling destroy(), and potentially quitting the application. Returns true on success, false if it has a parent window (in which case the top level window should be closed instead).

Here is the caller graph for this function:

◆ exposeEvent()

void QWindow::exposeEvent ( QExposeEvent * ev )

protectedvirtual

The expose event (ev) is sent by the window system when a window moves between the un-exposed and exposed states.

An exposed window is potentially visible to the user. If the window is moved off screen, is made totally obscured by another window, is minimized, or similar, this function might be called and the value of isExposed() might change to false. You may use this event to limit expensive operations such as animations to only run when the window is exposed.

This event should not be used to paint. To handle painting implement paintEvent() instead.

A resize event will always be sent before the expose event the first time a window is shown.

Here is the caller graph for this function:

◆ format()

QSurfaceFormat QWindow::format ( ) const

overrideprivatevirtual

Returns the actual format of this window.

After the window has been created, this function will return the actual surface format of the window. It might differ from the requested format if the requested format could not be fulfilled by the platform. It might also be a superset, for example certain buffer sizes may be larger than requested.

Note: Depending on the platform, certain values in this surface format may still contain the requested values, that is, the values that have been passed to setFormat(). Typical examples are the OpenGL version, profile and options. These may not get updated during create() since these are context specific and a single window may be used together with multiple contexts over its lifetime. Use the QOpenGLContext's format() instead to query such values.

◆ startSystemMove

bool QWindow::startSystemMove ( )

slot

Start a system-specific move operation.

Since: 5.15

Calling this will start an interactive move operation on the window by platforms that support it. The actual behavior may vary depending on the platform. Usually, it will make the window follow the mouse cursor until a mouse button is released.

On platforms that support it, this method of moving windows is preferred over setPosition, because it allows a more native look-and-feel of moving windows, e.g. letting the window manager snap this window against other windows, or special tiling or resizing behavior with animations when dragged to the edge of the screen. Furthermore, on some platforms such as Wayland, setPosition is not supported, so this is the only way the application can influence its position.

Returns true if the operation was supported by the system.

References d, and Q_UNLIKELY.

◆ startSystemResize

bool QWindow::startSystemResize ( Qt::Edges edges )

slot

Start a system-specific resize operation.

Since: 5.15

Calling this will start an interactive resize operation on the window by platforms that support it. The actual behavior may vary depending on the platform. Usually, it will make the window resize so that its edge follows the mouse cursor.

On platforms that support it, this method of resizing windows is preferred over setGeometry, because it allows a more native look and feel of resizing windows, e.g. letting the window manager snap this window against other windows, or special resizing behavior with animations when dragged to the edge of the screen.

edges should either be a single edge, or two adjacent edges (a corner). Other values are not allowed.

Returns true if the operation was supported by the system.

◆ active

QWindow::active

read

the active status of the window

Since: 5.1

See also: requestActivate()

Definition at line 91 of file qwindow.h.

◆ contentOrientation

QWindow::contentOrientation

readwrite

the orientation of the window's contents

This is a hint to the window manager in case it needs to display additional content like popups, dialogs, status bars, or similar in relation to the window.

The recommended orientation is QScreen::orientation() but an application doesn't have to support all possible orientations, and thus can opt to ignore the current screen orientation.

The difference between the window and the content orientation determines how much to rotate the content by. QScreen::angleBetween(), QScreen::transformBetween(), and QScreen::mapBetween() can be used to compute the necessary transform.

The default value is Qt::PrimaryOrientation

Definition at line 94 of file qwindow.h.

Referenced by QIOSWindow::QIOSWindow().

◆ flags

QWindow::flags

readwrite

the window flags of the window

The window flags control the window's appearance in the windowing system, whether it's a dialog, popup, or a regular window, and whether it should have a title bar, etc.

The actual window flags might differ from the flags set with setFlags() if the requested flags could not be fulfilled.

the modality of the window

A modal window prevents other windows from receiving input events. Qt supports two types of modality: Qt::WindowModal and Qt::ApplicationModal.

By default, this property is Qt::NonModal

◆ opacity

QWindow::opacity

readwrite

The opacity of the window in the windowing system.

Since: 5.1

If the windowing system supports window opacity, this can be used to fade the window in and out, or to make it semitransparent.

A value of 1.0 or above is treated as fully opaque, whereas a value of 0.0 or below is treated as fully transparent. Values inbetween represent varying levels of translucency between the two extremes.

The default value is 1.0.

Referenced by QIOSWindow::QIOSWindow(), and QCocoaWindow::isOpaque().

◆ title

QWindow::title

readwrite

the window's title in the windowing system

The window title might appear in the title area of the window decorations, depending on the windowing system and the window flags. It might also be used by the windowing system to identify the window in other contexts, such as in the task switcher.

Referenced by QDockWidget::changeEvent(), setTitle(), and QCocoaWindow::setWindowFlags().

◆ visibility

QWindow::visibility

readwrite

the screen-occupation state of the window

Since: 5.1

Visibility is whether the window should appear in the windowing system as normal, minimized, maximized, fullscreen or hidden.

To set the visibility to AutomaticVisibility means to give the window a default visible state, which might be fullscreen or windowed depending on the platform. When reading the visibility property you will always get the actual state, never AutomaticVisibility.

Definition at line 92 of file qwindow.h.

Referenced by QQuickWindowQmlImpl::QQuickWindowQmlImpl(), QQuickWindowAttached::visibility(), and QQuickWindowAttached::windowChange().

◆ visible

QWindow::visible

readwrite

whether the window is visible or not

This property controls the visibility of the window in the windowing system.

By default, the window is not visible, you must call setVisible(true), or show() or similar to make it visible.

Note: Hiding a window does not remove the window from the windowing system, it only hides it. On windowing systems that give full screen applications a dedicated desktop (such as macOS), hiding a full screen window will not remove that desktop, but leave it blank. Another window from the same application might be shown full screen, and will fill that desktop. Use QWindow::close to completely remove a window from the windowing system.
